Part Number:



Riffraff Diesel Billet Intake Manifold Plenums for Ford 7.3L 94-03

Our Gen 2 billet aluminum intake manifold plenums are 100% made in the USA from USA materials.

An engineered design that addresses several issues at once: 

- Pair of 6061 Billet Aluminum Plenums - No more sheet metal to bend
- Made In the USA!
- Anodized Black and available in custom colors upon request
- Larger intake mouth to accomodate flow
- Countersunk mounting hardware for seamless install
- Viton O-ring seal rather than RTV - Tested at over 100psi
- Works with both dual and single HPOP's
- Billet spacers for GPR and GPCM brackets
- Plenum mouth O.D. is machined to retain intake "Y" better for T4 style kits

If you are looking for a true billet solution at an economical price, then this is your product.

*Will not fit 94-Early 99 with stock style turbo. 94-96 have 8 mounting bolts, and 97-03 have 10 mounting bolts. Make sure you check to make sure you have selected the correct ones. Provision for the AIH ground, and passenger side fuel line clamp has not been made in this kit as normally they have already been deleted. 



*Note: Anodized Color on Aluminum can be discolored / damaged by chemical engine cleaners. Use only soap and water to clean.

    I just did a complete upgrade for my early 99 7.3. These billet intakes and the T500 were just what I needed to make sure that my 7.3 will continue to maintain its well deserved title, "the work horse."

    Bought a set of these for my truck and they are awesome. Quality is top shelf. The instructions tell you how to go about the install. I am upgrading my truck with what I consider will get me through another 17 years of service. Clay at Riff Raff is a great help to us Aussies.

    Couldn't see how to make them better

    Way more rigid than stock. A small hose barb is designed in which seems way better than the smooth stock design.

    Intake Plenums

    These things look amazing and are very well built. I decided to get these since I was doing the top end of the engine. They install pretty easy if you already have everything off but removing the old silicon is a huge PAIN.

    Also, the torque is in inch pounds not foot pounds. Everything I touched was foot pounds and I justified the rating by telling myself it’s billet and can probably take it and completely missed the inch rating until I stripped a few bolts.
